Xia, Rongjiao; Guo, Tao; Chen, Mei; Su, Shijun; He, Jun; Tang, Xu; Jiang, Shichun; Xue, Wei published the artcile< Synthesis, antiviral and antibacterial activities and action mechanism of penta-1,4-dien-3-one oxime ether derivatives containing a quinoxaline moiety>, Category: chlorides-buliding-blocks, the main research area is antiviral antibacterial pentadienone oxime ether.
A series of penta-1,4-dien-3-one oxime ether derivatives containing a quinoxaline moiety were synthesized and their antibacterial and antiviral activities were evaluated. Bioassay activity indicated that some of the compounds displayed significant antibacterial and antiviral activities. In particular, some title compounds were found to show remarkable antiviral activities against Tobacco mosaic virus (TMV). Compound 6i showed remarkable curative, protective and inactivation activity against TMV, with a 50% effective concentration (EC50) of 287.1, 157.6 and 133.0μg mL-1, resp. These results were better than or comparable to those of ningnanmycin (356.3, 233.7 and 121.6μg mL-1, resp.). Microscale thermophoresis (MST) also showed that the binding of compound 6i to TMV coat protein (TMV-CP) gave a Kd value of 0.115 ± 0.092μmol L-1, which was better than that of ningnanmycin (0.523 ± 0.254μmol L-1). Meanwhile, the EC50 values of compound 6k against Xanthomonas axonopodis pv. Citri (Xac) and Xanthomonas oryzae pv. oryzae (Xoo) were 16.8 and 33.4μg mL-1 resp., and that of compound 6i against Ralstonia solanacearum (Rs) was 33.9μg mL-1. These results were better than those of bismerthiazol (44.3, 42.5 and 62.4μg mL-1, resp.). The mechanism of antibacterial action of compound 6k against Xac was analyzed through SEM (SEM). This study indicated that the title compounds are valuable in the search for novel agrochems.
New Journal of Chemistry published new progress about Antibacterial agents. 611-19-8 belongs to class chlorides-buliding-blocks, and the molecular formula is C7H6Cl2, Category: chlorides-buliding-blocks.
